Duobinary Encoder and Driver Amplifier

Features
Device Diagram
The iT6144 is a RoHS-6-compliant integrated duobinary encoder and driver in a compact,
surface-mount package for optical 300-pin module and linecard transponders used in
long-haul applications. The device converts an electrical 10 Gb/s NRZ signal into an
equivalent duobinary signal, then amplifies it to drive a “filtered” LiNbO3 modulator. The
iT6144’s duobinary output level is adjustable from 6 to 10.5 Vpp, which is sufficient to
reach 2*Vpi of most LiNbO3 modulators and provide margin for loop control to track
variations caused by temperature and aging. Single-ended clock and data inputs
eliminate the need for phase-matched traces, simplifying the board layout. The clock
input and duobinary output are AC-coupled in the package. The data input should be AC-
coupled outside the package. The device is housed in a rugged, RoHS-6-compliant,
ceramic package.
